Low Price Stainless Steel Bearing Bushings

   Stainless Steel bearings compared with ordinary bearings, not onlt material has obvious 

advantages, but also in the process, the accuracy of the control, more than ordinary bearings to 

be more stringent. In the course of work stainless steel bearings work stable, low noise, 

corrosion-resistance, widely used.

    Product Features:

    Bearing rings and rolling materials used AISI SUS440C stainless steel ( domeatic grade: 

9Cr18Mo, 9Cr18 ) by vacuum quenching and tempering treatment, cage and sealing frame material 

using AISI304 stainless steel ( domestic grade: 0Cr18Ni9 ). Stainless steel bearings compared with ordinary bearing steel, there is a stronger anti-rust, anti-corrosion, select the appropriate 

lubricant, dust over, etc, can be -60 ℃~300 ℃ environment. Stainless steel deep groove ball 

bearings can withstand moisture and a number of other media caused by corrosion. This type of 

single-role deep groove ball bearings and carbon chromium ( rolling bearing ) steel manufacturing 

standard deep groove ball bearings, with a deep bearing raceway groove, bearing raceway and the 

ball between the high degree of cooperation. Stainless steel bearings because of high mechanical 

strength, load capacity, widely used in food processing, medical equipment, pharmaceutical 


    The main purpose:

    Medical equipment, low temperature engineering, optical instruments, high-speed machine 

tools, high speed motors, printing machinery, food processing machinery.


    1.Excellent corrosion resistance: stainless steel bearings are not easy to rust, with a 

strong corrosion resistance.

    2.Can be washed: stainless steel bearings can be washed down without having to re-lubricating 

oil to prevent rusting punishment.

    3.Can run in the liquid: due to the material used, we can run the bearings and bearings in 

the liquid. 

    4.The slow drying rate: AISI316 stainless steel, do not need oil or grease anti-corrosion 

protection. Therefore, if the speed and load are low, there is  no need for lubrication.

    5.Health: Stainless steel natural clean, no corrosion.

    6.High heat resistance: Stainless steel bearings are equipped with high temperature polymer 

cage or not in a complete complement structure of the cage, can run at a higher temperature range 

of 180 °F to 1000 °F.( Need to match high temperature grease )

    Reason for stainless steel bearing failure:

    Stainless steel bearing fracture failure is mainly due to defects and overload two factors. 

When the external load exceeds the material strength limit caused by part fracture known as 

overload fracture. The cause of the overload is that the host is faulty or improperly installed. 

Bearing parts f the micro-cracks, shrinkage, bubbles, large foreign debris, overheating tissue 

and local burns and other defects in the impact of overload or severe vibration will also cause 

damage in the defect, known as defective fracture. It should be noted that the bearing in the 

manufacturing process, the raw materials into the factory re-inspection, forging and heat 

treatment quality control, processing process control can be correctly analyzed by the instrument 

whether the exsistence of defects in the future must still strength control. But in general, the 

failure of the stainless steel bearings usually occurs mostly for overload failure.
